That looks like a fine machine- it takes me back to mine which I sold 7 or 8 years ago (has it been that long?)

Mine only ever made 55hp at the rear wheel with the weber carb, slip ons, and the top of the airbox cut off, so you're doing pretty well with those numbers.

1. Brakes- Mine worked very well- comparable to the newer Brembos on my other Ducatis- I had stainless lines and aggressive pads. When the bike would sit for the winter, the rotors would oxidize unevenly and give something like the strange feedback you describe.

2. Hesitation- Yeah, the weber always had a bit of that. My solution was to ride flat out all the time. Easy to do with only 55hp!

3. Clutch drag- There was a fair amount of drag, and neutral was always hard to find. Mobil 1 20/50 made it a lot better. I could always tell when the oil needed to be changed because shifting and clutch performance would always drop off around 1,500-2,000 miles after an oil change.

Hope that helps!
